Plastic roof shingle

Abstract

The roof shingle is made of plastic and has a generally planar nailing portion and a generally planar exposable portion extending generally coplanarly from the nailing portion. An imaginary first axis defines the nailing portion from the exposable portion. The shingle has a fold area extending generally centrally through the nailing portion and the exposable portion along a second axis generally at a right angle to the first axis. For the ridge line of the roof, the shingle may be folded along the fold area to produce a V-shape for installation along the ridge line, without having to cut the shingle or use a different design.

1 . A roof shingle, made of plastic and comprising:
 a generally planar nailing portion; and   a generally planar exposable portion extending generally coplanarly from said nailing portion, defined from said nailing portion by an imaginary first axis extending across said shingle;   
     wherein said shingle has a fold area extending generally centrally through said nailing portion and said exposable portion along a second axis generally at a right angle to said first axis. 
   
   
       2 . A roof shingle as in  claim 1 , wherein said fold area is defined by a least one rib on an underside of said shingle extending along said second axis, with no ribs running across said second axis in said fold area. 
   
   
       3 . A roof shingle as in  claim 1 , wherein said fold area is defined by a plurality of generally parallel ribs on an underside of said shingle extending along said second axis, with no ribs running across said second axis in said fold area. 
   
   
       4 . A roof shingle as in  claim 1 , wherein a substantial portion of said shingle has ribs across an underside thereof, not extending into said fold area. 
   
   
       5 . A roof shingle as in  claim 2 , wherein a substantial portion of said shingle has ribs across an underside thereof, not extending into said fold area. 
   
   
       6 . A roof shingle as in  claim 3 , wherein a substantial portion of said shingle has ribs across an underside thereof, not extending into said fold area.
